Telkom bad service

I have settled my Telkom account through VVM Collections in October 2019 and I have a paid up letter from VVM. However, my credit check on the Credit bureau still reflects that I still owe Telkom. I am very disappointed because Telkom never updated my details on the Credit Bureau since October 2019 and this account still reflects as missed payments, dropping my credit score below average. Telkom, sort this out with VVM Collections and update my details urgently. Telkom service is very poor in terms of customer service, I wouldn't recommend Telkom to any person after they have failed to do their job and failed to update my details as soon as they received their full payment.
